Specification of Letters Patent.

Patented Feb. 23, 1909.

Application filed April 7,1908. Serial No. 425,635.

To all whom it may concern:

Be it known that I, Monrz KLAUBER, a sub- 'ect of the Austrian Emperor, and resident of randelgasse 12, Prague, Bohemia, Austria- Hungary, have invented certain new and use- Improvements 1n Submarme Mines, of wh ch the following is a specification.

'not explode, on the other hand.

The arrangement consists essentially of a percussion hammer under the action of a spring, and'secured in its position by a looking device which is released when any ship comes "into contact with the mine and allows the hammer'to knock against the ignition Wad, so that the mine charge is fired and explodes. Further, in the interior of the mine a movable protectin shield is laced which can be moved bac liward and forward from the outside, and. can be pushed over the ignition wad so that it protects the latter from the hammer and receives the blow of the sameitself. By this arrangement absolute safety from explosion is obtained when laying mines, and it is also possible when the other conditions allow it, to make the mine safe from explosion by shifting the gfotecting shield, even when the mine has can in the water a long time, and without having to bring it to the surface, and later on to prepare it for exploding again by withdrawing the protecting shield.

On the accompanying drawings, the improvements according to the present invention are illustrated.

Figure 1 is a view in perspective, and partly a vertical section through the mine respectively. Fig.2 is a horizontal section through line II of Fig. 1. Figs. 3-8 show two forms of construction of the safety arrangement. vertical section respectively of one form of construction. Fig. 4 is a plan and horizontal section res ectively. Fig. 5 is a vertical Fig. 6

section throug line 11-11 of Fig. 3. shows a second form of construction'of'the 'safety arrangement, being a side view and vertical section respectively, Fig. 7 is a plan and horizontal section respectively.

Fig. 3 is a side View and a Fig. 8 is a vertical section throughline III III of Fig. 6.

On the case 1 of the mine which is anchored in the usual manner a known form of glass cap 2 is placed. Directly below the latter inside the case lisa small space 3 which is made tight below by means of a leather bottom 4 or similar device. In the center of this bottom part 4 is a plate 5 which should preferably be constructed of wood. On the plate 5 a rod 6 is fixed, which is guided vertically in a tube 7 without friction, the tube being attached to the partition 9 by means of the feet 8. Further, on this partition 9 an axle 10 is firmly attached on which the percussion hammer 11 turns. S rings 12 are placed round the axle 10 whic continually exert an effort to bring the hammer 11 into the dotted position shown in Fig. 2.

In order to maintain the hammer 11 in the position shown in'Fig. 1, where is under the tension of the'spring, a detent arm T113is placed above it, the end of which is linked to an eye 14, while the other end is held by a catc 15. The latter is fixed to the partition 9 so that it can turn and carries a plate 16 on one side, which is at right angles to the bowformed catch 15. The rod 6 rests on this plate 16. If a ship now comes into contact with the mine, the shock will break the glass cap 2 and the water will flow through the opening formed, intothe space 3. Hereb the elastic bottom 4 carrying the plate 5 Wi be bent down and consequently the rod 6 will move downward in the tube 7. The same will thus press downward on the plate 16, whereby the bow-formed catch 15, which is attached to the latter, will be turned and drawn from the end of the detent arm 13. The last. will thus be released so that the hammer 13 can fall into the dotted position shown in Fig. 2, by the action of the springs 12. In this way the end of the hammer 17 knocks against the igr'n'tion-priming 18 of a cartridge laced in the partition 9, whereu 051E116 dharge 19 is fired and the mine ex- 0 e p In order to be able to lay the mine and remove the same without danger, for to place the same temporarily out of action the following arrangement is provided. Inside the case of themine 1 a plate 20 is laced above to a rod 23 which passes through the case of the mine and has a handle 24 at its end, by means of which the plate or shield20 inside the mine can be moved backward and forward. At the point at which the rod 23 projects from the mine a plate 25 is fixed to the case 1 through which the rod 23 also passes. A plate 26isfixed to the rod 23, the construction of which is similar to the late 25. The handle 24, the plate 26, the ro 23 and the shield 20 are all connected together. In order to prevent the entry of .water at the point where the rod 23 enters, the mine, both plates 25 and 26 are connected together and made watertight by means of leather bellows 27, or similar arrangement, so that a thoroughly watertight packing is insured.

l or fixing the protecting shield 20 in its end positions rails 28 are placed on both sides of the rod 23 and parallel to it, these rails being provided with corresponding holes 29.

A rod 30 is passed through the holes 29 and a ring 30 on the handle, whereby the plate 20 is fixed in its position. By the use of stops 32, 33 the movement of the plate 20 can be limited, thus allowing a safe adjustment of the same in every case.

In the form of construction shown in Figs. 3-5 the protecting shield 20, in order to protect the cap 18 against the action of the percussion-hammer, must be pushed toward the inner part of the mine. The arrangement can, however, also be made as shown in higs. 68 so that the shield 20 must be drawn outward toward the mine case in order to cover the ca 18. In the first case, the hammer 11 will all-onto the ca 18 in the direction of movement of the s 'eld 20 (Fig. 4), whereas in the last case it moves vertically to the shield 20, as shown in Big. 7. If Whenlaying or removing the mine or for any other reason it is desired to put the mine out of action, it is only necessary to move the rotecting shield over the ignition-cap an to secure the former in its osition in the manner described. An acci ental blow from the -'hammer will thus be caught by the safety shield.

By removing the safety shield from the ignition-cap the mine can again be prepared for o eration'at any time.
